Why use cluster bombs?

The modern cluster bomb dates back to the 1960s and was extensively
used in Vietnam, the Gulf War and the recent conflict in Kosovo.

A typical cluster bomb is made up of a container or
dispenser - essentially a bomb-shaped cylindrical casing - which carries a large
number of sub-munitions or bomblets to the target area.

There are a huge variety of cluster bombs manufactured by a number of
countries.

But they work on the same principle: after being dropped from an
aircraft, the container opens, either scattering or ejecting the
sub-munitions over a large area.

The sub-munitions can be of a variety of types:

Anti-personnel bomblets that kill or maim by fragmentation

Anti-tank sub-munitions to be used against armour or vehicles

So-called combined effect munitions that contain both anti-armour
weapons with an incendiary capacity

Various kinds of landmines.

Cluster bombs have the great advantage that they can be used against a
variety of targets covering significant areas, rather than, for
example, pin-pointing individual armoured vehicles.

The US used a staggering number of such bombs in south-east
Asia. Pentagon estimates suggest that some 285 million sub-munitions
were dropped on Cambodia, Vietnam and Laos.

One of the great problems with these weapons though is the tendency of
many of the bomblets to fail to explode - a point highlighted by the
UK Working Group on Landmines' study.

This is especially the case when the weapons are dropped from medium
or high altitude, when the bomblets tend to drift in the wind and can
land a long way from the intended target.

The fact that some bomblets may be brightly coloured and appear
interesting to children also causes many accidents in the aftermath of
conflicts.

Air warfare experts insist that the bombs still have a useful role to
play - especially in a full-scale war.

But the very limited nature of many recent conflicts has led many
western air forces to seek more accurate, less indiscriminate weapons,
which would be less likely to present a continuing danger once the
fighting is over.
